Abstract
A toy automobile includes wheels, axles connecting the wheels, a holding plate, a control circuit, a sensor, and struts and drive trains corresponding to the wheels. Each strut includes a pivoting strut and a support strut pivoted to each other, one ends of the pivoting strut and the support strut are slidably mounted on the axles. The other end of the support strut slidably resist at the bottom surface of the holding plate. Each drive train is connected with another end of the pivoting strut. When the holding plate is tilted relative to a horizontal reference plane, the control circuit controls the drive trains to drive the pivoting struts at a lower end of the holding plate, the pivoting struts rotate and lift the support struts correspondingly, thus to lift the lower end and make the holding plate parallel to the horizontal reference plane.
